Definition

1. Noun:
   • Isodiaphere: In nuclear physics, an isodiaphere refers to one of a group of nuclides that have the same difference between their number of neutrons and number of protons (i.e., the same neutron excess). These nuclides share an identical value for (N - Z), where N is the number of neutrons and Z is the number of protons.

Usage Examples

• Noun:
  • Các hạt nhân này là đẳng dị của nhau. (These nuclei are isodiapheres of each other.)
  • Thuật ngữ "đẳng dị" được sử dụng trong vật lý hạt nhân. (The term "isodiaphere" is used in nuclear physics.)

Advanced Usage

• The concept is primarily used in technical discussions of nuclear stability, radioactive decay series, and the organization of nuclides.

Variants and Related Words

• Đẳng tích (adj): isochoric (at constant volume).
• Đẳng nhiệt (adj): isothermal (at constant temperature).
• Đẳng hướng (adj): isotropic (having identical properties in all directions).

Synonyms

• Isodiaphere: The direct and most precise English equivalent.

Notes on Usage

• "Đẳng dị" is a highly specialized scientific term. It is not used in everyday conversation and is almost exclusively found in academic texts on nuclear physics or chemistry.
• It is a compound word formed from "đẳng" (meaning equal, iso-) and "dị" (meaning different, disparate), reflecting the concept of having an equal difference.
