“…mainly narrow peaks, which were interpreted as strength apparently of other character than isovector electric dipole [8,9,[21][22][23]. Even if it has minor importance for total photon absorption and the sum rules, it may influence the decay of the compound nucleus and consequently also the cross sections of capture reactions.…”

“…The low-energy tail of the GDR below S n is of particular interest because of an extra enhancement of observed E1 strength. This pygmy dipole resonance (PDR) [7][8][9], has been found, for example, in 76 Se [10], 78 Se [11], nuclides around N = 50 [12][13][14], around N = 82 [15][16][17][18], and in 181 Ta [19].…”

“…(i) In the first place, there are several works presenting calculations of fission barrier heights, using semimicroscopic models based on the Strutinsky [26][27][28] and Hartree-Fock [29,30] methods. However, absolute values for barrier heights from these theoretical approaches, are systematically lower than those obtained from the fitting of cross sections by means of statistical model calculations [11][12][13][14][15][16]23,24]. (ii) In the second place, and considering that the uncertainties associated with our measurements [15] are modest, we note that small differences between the selected barrier heights entering our model calculations could eventually destroy the agreement between level groups (and level voids) and the corresponding structures in the measured cross sections.…”

“…In fact, this drawback explains why theoretically obtained fission barriers are not generally used in statistical calculations of cross sections. Moreover, level densities at all the extreme points of the fission path are estimated from phenomenological formula [11][12][13][14][15].…”
