- ^ mBr – Isomer nuklir tereksitasi.
- ^ ( ) – Ketidakpastian (1σ) diberikan dalam bentuk ringkas dalam tanda kurung setelah digit terakhir yang sesuai.
- ^ # – Massa atom bertanda #: nilai dan ketidakpastian yang diperoleh bukan dari data eksperimen murni, tetapi setidaknya sebagian dari tren dari Permukaan Massa (trends from the Mass Surface, TMS).
- ^
Mode peluruhan:
- ^ Simbol miring tebal sebagai anak – Produk anak hampir stabil.
- ^ Simbol tebal sebagai anak – Produk anak stabil.
- ^ ( ) nilai spin – Menunjukkan spin dengan argumen penempatan yang lemah.
- ^ # – Nilai yang ditandai # tidak murni berasal dari data eksperimen, tetapi setidaknya sebagian dari tren nuklida tetangga (trends of neighboring nuclides, TNN).
