Isobaric analog states in odd-odd nuclei

POSTER

Abstract

We calculate the excitation energies of Isobaric Analog states in selected odd-odd nuclei. We use the formula for e.g. $^{96}$Ag E{*}(J=0$^{+}T=2)$= BE($^{96}$Ag) - BE( $^{96}$Pd) +V$_{C}$ where V$_{C}$=E$_{1}$ Z / A$^{(1/3)}$ + E$_{2}$ ; E$_{1}$ =1.441 MeV ; E$_{2}$ =-1.06 MeV. We list the following in MeV. ( $\Delta(BE),$V$_{C},$E{*}(calc), E{*}(single j),E{*} (multij shell model), Experiment) $^{44}$Sc (4.435, 7.308, 2.873, 3.047, 3.418, 2.779) $^{46}$Sc (2.160, 7.148, 5.024 , 4.949, 5.250, 5.022 ) $^{52}$Mn (5..494, 8.399, 2.905, 2.774, 2.731, 2.926) $^{60}$Cu ( 6.910, 9.430, 2.520, 2.235, 2.726 2.536 ) $^{94}$Rh (10.386, 13.043, 2.657, 1.990 , 3.266,.........) $^{96}$Ag (12.342, 13.574, 1.142, 0.900, 1.9172,........) The experimental energies of the isobaric analog states are known for the lighter nuclei but not for $^{94}$Rh or $^{96}$Ag. If we use the semi-empirical mass formula of Wapstra (2003) one gets the excitation energy in $^{96}$Ag to be 0.367 MeV.
