If any readers are looking for opportunities to study for a funded master's degree in nuclear physics, an email I received earlier this week might just have what you are after. It's a 2-year taught master's degree course entitled (deep breath) Erasmus Mundus Joint Master Degree in Nuclear Physics (EMJMDNP). The email says that "the course is supported by EACEA Agency of European Union with full scholarships (including travel costs and health insurance)"
The degree is co-taught across several universities across Europe, and from what I can see all students will spend some time in each of Spain, France, and Italy. It looks pretty interesting, and well worth considering as a next step if you have just finished your bachelor's degree and nuclear physics takes your fancy. Tell them I sent you :-)
