Gamma spectrum of 106mAg

Abstract

The gamma spectrum of the decay of 106mAg (8 d) was measured with a Ge(Li) detector. The following energies in keV and relative intensities (in parentheses) were determined: 194.93 (6), 221.51 (83), 228.53 (29), 328.27 (18), 375.1 (3), 390.90 (43), 406.00 (152), 418.6 (7), 429.46 (161), 450.80 (310), 474.2 (12), 511.77 (1000), 586.0 (9), 600.88 (23), 616.05 (236), 645.5 (18), 680.3 (25), 703.3 (52), 717.1 (320), 748.2 (227), 792.8 (65), 803.9 (124), 807.5 (42), 824.5 (160), 847.5 (45), 875 (7), 956 (8), 1019.7 (9), 1045.7 (285), 1053 (11), 1121 (9), 1127.8(106), 1199.1 (106), 1222.8 (61), 1394.2 (17), 1527.0 (155), 1565 (8), 1572.1 (70), 1691 (0.5), 1722.1 (15), 1770 (0.6), 1793 (0.6), 1837.9 (20) and 2082 (0.2).All but two of the transitions were placed into a decay scheme with the following levels (in keV): 511.77 (2+), 1127.8 (2+), 1228.9 (4+), 1557.3 (3+, 4+), 1931.8 (3+, 4+), 2076.7 (3+, 4+), 2083.8 (3−), 2282.0? (3+, 4+), 2305.3 (4−), 2350.2 (3+, 4+), 2365.2? (3+, 4+), 2756.2 (5+) and 2951.1 (5+).El espectro gamma del decaimiento de 106mAg (8 d) se midió con un detector de Ge(Li). Se determinaron las siguientes energías en keV e intensidades relativas (entre paréntesis): 194,93 (6), 221,51 (83), 228,53 (29), 328,27 (18), 375,1 (3), 390,90 (43), 406,00 (152), 418,6 (7), 429,46 (161), 450,80 (310), 474,2 (12), 511,77 (1000), 586,0 (9), 600,88 (23), 616,05 (236), 645,5 (18), 680,3 (25), 703,3 (52), 717,1 (320), 748,2 (227), 792,8 (65), 803,9 (124), 807,5 (42), 824,5 (160), 847,5 (45), 875 (7), 956 (8), 1019,7 (9), 1045,7 (285), 1053 (11), 1121 (9), 1127,8 (106), 1199,1 (106), 1222,8 (61), 1394,2 (17), 1527,0 (155), 1565 (8), 1572,1 (70), 1691 (0,5), 1722,1 (15), 1770 (0,6), 1793 (0,6), 1837,9 (20) y 2082 (0,2).Todas menos dos de las transiciones se colocaron en un esquema de descomposición con los siguientes niveles (en keV): 511,77 (2+), 1127,8 (2+), 1228,9 (4+), 1557,3 (3+, 4+), 1931,8 ( 3+, 4+), 2076,7 (3+, 4+), 2083,8 (3−), 2282,0? (3+, 4+), 2305,3 (4−), 2350,2 (3+, 4+), 2365,2? (3+, 4+), 2756.2 (5+) y 2951.1 (5+).
