Studies of chirality in the mass 80, 100 and 190 regions

Abstract

A brief survey of results of studies of nuclear chirality in the mass 80 and 190 region at iThemba LABS is given, before looking at the case of 106Ag in detail. Here, the crossing of a pair of candidate chiral bands is re-interpreted as the crossing of a prolate band by an aligned four-quasiparticle band

Chirality in atomic nuclei: 2013

“…13 Experimentally, the evidences of chiral doublet bands have been extensively reported in the A ≈ 80, 100, 130 and 190 mass regions [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] (see Refs. [34][35][36]. However, it should be pointed out that the lifetime measurements which are essential to extract the absolute electromagnetic transition probabilities are still rare for the candidate chiral bands.…”

Recent progress in multiple chiral doublet bands *

“…Thus far, such chiral doublet bands have been reported in the 80 [2][3][4], 100 [5][6][7][8][9][10][11][12], 130 [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], and 190 [30][31][32][33][34][35][36] mass regions of the nuclear chart. For details, see recent reviews on nuclear chirality and related topics [37][38][39][40][41][42][43][44][45] or data tables [46].…”
