Cooling effect in emissions of103mRh excited by bremsstrahlung

“…In the previous reports, interesting anomalies with the characteristic emissions, including Kα, Kβ and γ, at room temperature from the long-lived nuclear state of 103m Rh excited by bremsstrahlung irradiation have been observed [1][2][3]. There are several methods to excite the long-lived nuclear states with different species of nuclei, as reported in the literature: by coulomb excitation [4], the (γ,γ') bremsstrahlung excitation [5][6][7][8], the (γ,γ') photo-activation [9], and the (n,γ) neutron excitation [10]. Although 107m Ag [5,6,7,9], 109m Ag [5,6,9], and 103m Rh [8,9,10] obtained by (γ,γ') and (n,γ) have been investigated, none of them addressed the issue of anomalous emissions as reported in our previous works [1][2][3] and the study presented in this paper.…”

For the inversion density of a two-level model of the 103 Rh isotope excited by the bremsstrahlung irradiation, linear and nonlinear regimes have been identified and reported [1].…”

Generation of long-lived isomeric states via bremsstrahlung irradiation

“…Is there any other effective method to achieve isomeric excitation? Coulomb excitation [7], (γ,γ') of the bremsstrahlung excitation [8][9][10][11], (γ,γ') of the photo-activation [12], and (n,γ) of the neutron excitation [13] are possible methods.…”

“…Two methods of (γ,γ') are considered to be more suitable for our application, since coulomb excitation generates more heat in samples. It is noted that 107 Ag [8,9,10,12], 109 Ag [8,10,12], 103 Rh [11,12,13] created by (γ,γ') and…”
