Summary. --A sample of Be 125m2Te containing (4.9 _+ 1.5). 10 TM atoms/era 3 of 125"~Te was obtained in a reactor by neutron activation of polycrystalline beryllium telluride Be124Te. The ratio of the number of 109.27keV photons emitted in the 125~ZTe + hv--,125mlTe + 2hv transition due to attainment of the MSssbauer conditions (at T = 10 K) to the total number of photons produced in the sample at T = 300K was measured to be e~p = Ar162 = 0.0045 + 0.0030. Independent measurements of the intensity of the two-photon 218.54 keV line at 10 K in the same sample yielded a value of 0.0023 + 0.0004 for e~p. Under the conditions of our experiment in the moving-wave approximation (i.e. in the framework of non-stationary optics) the theory predicts the value etheo r =-~coh(10K)/-~non~oh (300 K) = 0.0018 + 0.0006 for the ratio of the superemission power of Te-125me nuclei at 10 K 2cob to the normal spontaneous emission power of these nuclei at 300 K -~non-coh-This value within the error coincides with e~p. The stimulated MSssbauer transition 123~Te + hv(88.46 keV)--~ 123miTe + 2hv(88.46 keV) in a polycrystalline sample of Mga TeO6 containing (3.4 -+ 0.7). 1019 atoms/cm 3 of 128~Te was also experimentally studied. The measured value e~p = (5 -+ 3). 10 -4 for this transition within the error coincides with a theoretical value ethc~r = 0.00023 obtained in the moving-wave approximation.

“…4) an angle independent ratio P2,/P(n=3.0 is determined. Using information from reactions with light ions [15] one may assume that N~ =6 and N 2=2 (see Ref,4). In addition one has to consider the average spin-multiplicity 2(j)+ 1 in the one-and two-nucleon transfer and with both factors a corrected value of EF = 20-40 can be estimated.…”

Pairing effects in quasi-elastic neutron transfer between Tin isotopes

The transfer of neutrons between low-lying states of Tin isotopes has been measured in the reaction 12~ ~ 112Sn at energies below the Coulomb barrier. The transfer probabilities are deduced as function of the classical minimum distance from transfer and scattering cross sections at different angles and two energies. At the smallest distances very large transfer probabilities, Pt=0.5, are observed for one-and two-neutron transfer. The two-neutron transfer is significantly enhanced as compared to a successive independent single-nucleon transfer. The definition of enhancement is discussed.

“…The reaction products were identified by plotting AE vs E 'd &. The measurements were calibrated internally using known [7,8] excitation energies in ' Er and with proton-transfer reactions on "' Sn targets, where the reaction products were measured at identical spectrometer settings and the known [9] energies of states in " ' 'Sb were used.…”

“…The previously identified [7] two-proton band IC =8+I 9 [514]+ -', [523]J has its bandhead I =8+ state at 3076 keV, and the Gallagher rule [10] predicts the E =1+P, [514] --, '[523]I band should be lower in energy, because like nucleons tend to couple to spin-zero pairs. The energy separation of the two bands is determined by the energy it takes to Aip one proton spin, which has been empirically determined [7] to be 400 keV for this nucleus.…”

The ' Ho (a, t) and ( He, d) reactions have been measured at beam energies of 40 and 25 MeV to look for the K =1+[9 [514] --[523]] two-proton band structure in '66Er. Reaction products were analyzed using a quadrupole-three-dipole spectrometer. Distorted-wave Born approximation predictions were used to extract candidate states with angular momentum transfer 1=5. The measured strengths of all the candidates for l =5 transitions were compared with the Nilsson fingerprint pattern of the K =1+ [ 2 [514] -2 [523]] band to identify the structure. No strong population of this configuration was found. At best two tentative candidates for the I =3+ and 4+ members of this band could be identified, which would represent at most 38% of the expected strength for this configuration. The bandhead for this tentative K =1+ excitation does not correspond to any I =1+ state observed in the Er(y, y') reaction. PACS number(s): 25.55. Hp, 21.10.Re, 27.70.+ q
